HIGH CURRENT AND EFFICIENCY RESULT FROM USING GRAPHITE OR DIAMOND CATHODE MATERIALS, ACCORDING TO RESEARCH PERFORMED AT APPLIED SCIENCES, INC. WHY? NOBODY KNOWS! ELLIOT KENNEL OF ASI SAYS THAT THE RESULTS MAY BE DUE TO RYDBERG EXCITED STATES CESIUM ATOMS PRODUCED IN THE PLASMA SPACE BETWEEN ELECTRODES. THE RYDBERGS ARE PRODUCED FROM CONTACT BETWEEN CESIUM AND SOME FORMS OF CARBON. IF THIS IS SO, HIGH POWER PLASMA SWITCHES AND/OR MORE EFFICIENT THERMAL-TO-ELECTRIC ENERGY CONVERTERS WILL RESULT. PHASE I WILL EXPLAIN WHY THE "RYDBERG CONVERTER" GIVES MORE THAN TWICE AS MUCH BANG PER BUCK THAN CONVENTIONAL NAME BRANDS, AND PHASE II WILL EXPLOIT THE BAND IN AN OPERATING DEVICE--EITHER A CONVERTER OR A HIGH POWER SWITCH (HAVEN'T DECIDED YET WHICH).
